Electrode Gap Bridging
ELECTRODE GAP BRIDGING
Electrode Gap Bridging
Loose deposits in the combustion chamber can cause electrode gap bridging. The deposits accumulate on the spark plugs during continuous
stop-and-go driving. When the engine is suddenly subjected to a high torque load, the deposits partially liquefy and bridge the gap between the
electrodes. This short circuits the electrodes. Spark plugs with electrode gap bridging can be cleaned and reused.
